Fix assert in ObjCARC optimizer when deleting retainBlock of null or undef.
The caller to EraseInstruction had this conditional:
// ARC calls with null are no-ops. Delete them.
if (IsNullOrUndef(Arg))
but the assert inside EraseInstruction only allowed ConstantPointerNull and not
undef or bitcasts.
This adds support for both of these cases.
